[Regionalization of federal health reporting using the example of diabetes surveillance : Aims and results of the discussion between the Robert Koch Institute and the federal states].

Insufficiently treated diabetes mellitus can lead to severe comorbidities. National and international analyses show a continuous increase in diabetes prevalence over the last decades. Currently, an indicator-based national diabetes surveillance system is implemented at the Robert Koch Institute (RKI) to monitor and report on diabetes development on the basis of available primary and secondary data.

Model structure of the immunodominant surface antigen of Eimeria tenella identified as a target for sporozoite-neutralizing monoclonal antibody.

Eimeria tenella is a coccidian parasite of great economical importance for poultry industry. The surface of Eimeria invasive agents, sporozoites and merozoites, is coated with a family of developmentally regulated glycosylphosphatidylinositol (GPI)-linked surface antigens (SAGs), some of them involved in the initiation of the infection process. Using 2D gel electrophoresis followed by mass spectrometry, an antigenic surface protein EtSAG1 (TA4) of E.

Extracellular calcium deficiency and ryanodine inhibit Eimeria tenella sporozoite invasion in vitro.

An in vitro assay system with Eimeria tenella sporozoites was used to study the effects of extracellular calcium and active agents affecting the invasion of parasites into host cells. At concentrations of 900 microM Ca(2+) and less the invasion rates were distinctly decreased. Ryanodine, a herbal alkaloid known for binding to internal Ca(2+) channels (ryanodine receptors), showed an inhibitory effect on E.
